4 5 Membrane Systems

NOXERIOR uses the principles of air separation by means of hollow- fibre membranes, which is a continuous process driven by the selective permeation of gases across the membrane wall of hollow polymer fibres. The hollow polymer fibres are packed together in a functional unit, called membrane module, which consists of a bundle of several thousand hollow fibres inside a casing. Normally membrane modules are installed in a parallel configuration, so that Plant control by a Local Control Panel each module output contributes proportionately to the capacity of (LCP) or directly by customer‘s DCS/ESD the system. Membrane modules with casings in aluminium, FRP or stainless steel The membrane technology is particularly suitable for the production of nitrogen or for dew point suppression of compressed air. Our membrane modules are the result of an extensive effort in R&D and set market standards in terms of productivity and efficiency. Besides, the productivity of a membrane module increases with the tempe- rature of the incoming feed air, which makes the process particularly suitable for operation at high ambient temperatures. Our membrane modules are available in various sizes in order to offer the most sui- table solution for each individual customer.

Membrane packages from NOXERIOR require very limited installa- tion space and therefore are particularly suitable for mobile units, offshore platforms or shipboard installations. Our membrane plants can be supplied inside cabinets, on skids or turn-key installed inside ISO freight containers. All components will be selected based on the local ambient conditions and the area classification of the installati- on site.

NOXERIOR is able to fulfil any specific requirement from the custo- mer. Whether it concerns the inclusion of the feed air system in our scope of supply, or the application of specific technical specifications for materials of the various components, local instrumentation and plant control, we can make the membrane system exactly as you want it.

Local instrumentation with either the HART® or the FoundationTM Fieldbus 6 communication protocol 7 Adsorption Systems

NOXERIOR also applies the adsorption technology by means of molecular sieves as an alternative process for air separation or air drying. An adsorption system typically contains either two single adsorption vessels (twin-tower systems) or a series of modules of two adsorption vessels (modular systems), where each vessel is fi l- led with an appropriate molecular sieve. These adsorption vessels are alternatively loaded with clean feed air in order to guarantee a continuous product fl ow. If one adsorption vessel is loaded, si- multaneously the other one is regenerated (desorption). The entire Adsorption vessels designed and process is generally known as Pressure Swing Adsorption (PSA) in certifi ed to CE, ASME, GOST or AS case of air separation and as heatless air adsorption drying in case of compressed air drying.

The adsorption technology is particularly suitable for the pro- duction of high purity nitrogen, oxygen or instrument air. Our PSA process for nitrogen or oxygen production and our heatless adsorption process for air drying are the result of an extensive eff ort in R&D and set market standards in terms of productivity and effi ciency. The volume of the adsorption towers will be defi ned specifi cally for each project in order to off er the best technical and economical solution.

Our PSA and adsorption air drying plants can be supplied inside cabinets, on skids or turn-key installed inside ISO freight conta- iners. All components will be selected based on the local ambient conditions and the area classifi cation of the installation site.

NOXERIOR is able to fulfi l any specifi c requirement from the custo- mer. Whether it concerns the inclusion of the feed air system in our scope of supply, or the application of specifi c technical specifi ca- tions for materials of the various components, local instrumentati- on and plant control, we can make the PSA or adsorption air drying plant exactly as you want it.
